Route learning and advertising parameters
Route learning and advertising parameters
You can configure the following learning and advertising parameters:
• Learning and advertising of RIPng default routes
• Advertising of IPv6 address summaries
• Metric of routes learned and advertised on a router interface
By default, the Brocade device does not learn IPv6 default routes (::/0). You can originate default
routes into RIPng, which causes individual router interfaces to include the default routes in their
updates. When configuring the origination of the default routes, you can also do the following:
• Suppress all other routes from the updates
• Include all other routes in the updates
Configuring default route learning and advertising
To originate default routes in RIPng and suppress all other routes in updates sent from Ethernet
interface 1/1/4, enter the following commands.
Brocade(config)# interface ethernet 1/1/4
Brocade(config-if-e10000-1/1/4)# ipv6 rip default-information only
To originate IPv6 default routes and include all other routes in updates sent from Ethernet interface
1/1/4, enter the following commands.
Brocade(config)# interface ethernet 1/1/4
Brocade(config-if-e10000-1/1/4)# ipv6 rip default-information originate
Syntax: [no] ipv6 rip default-information only | originate
The only keyword originates the default routes and suppresses all other routes from the updates.
The originate keyword originates the default routes and includes all other routes in the updates.
To remove the explicit default routes from RIPng and suppress advertisement of these routes, use
the no form of this command.
Advertising IPv6 address summaries
You can configure RIPng to advertise a summary of IPv6 addresses from a router interface and to
specify an IPv6 prefix that summarizes the routes.
If a route prefix length matches the value specified in the ipv6 rip summary-address command,
RIPng advertises the prefix specified in the ipv6 rip summary-address command instead of the
original route.
For example, to advertise the summarized prefix 2001:DB8::/36 instead of the IPv6 address
2001:DB8:0:adff:8935:e838:78:e0ff with a prefix length of 64 bits from Ethernet interface 1/1/4,
enter the following commands.
Brocade(config)# interface ethernet 1/1/4
Brocade(config-if-e10000-1/1/4)# ipv6 address 2001:db8:0:adff:8935:e838:78:
e0ff /64
Brocade(config-if-e10000-1/1/4)# ipv6 rip summary-address 2001:db8::/36
Syntax: [no] ipv6 rip summary-address ipv6-prefix/prefix-length
